“北麦南稻，南船北马”是以什么为分界线( )
A．秦岭—淮河
B．昆仑山
C．巴颜喀拉山—秦岭
D．大兴安岭
参考答案：A
解析： 本题考查地理常识。秦岭-淮河-线，就是我们常说的中国南北地理分界线，此线南北，无论是自然条件、农业生产方式，还是地理风貌以及人民的生活习俗，都有明显的不同。秦淮以北的大部分地区，河湖冬季结冰，年降水量较少，降水多几种在夏季，所以河流的水量不大，水位变化大，只有夏季才形成汛期，时间也比较短。，河流的含沙量较大。北方耕地为旱地，主要作物为小麦和杂粮，一年俩熟或俩年三熟；而在秦淮以南地区则正好相反，冬季不结冰，树木不落叶，一年四季常绿。河流的水量较大，水位变化不大，汛期时间长，河水含沙量较小。主要是水田，农作物主要是水稻和甘蔗、茶叶等也热带经济作物。一年俩熟或三熟。人们平常所说的“北麦南稻，南船北马”是这种差异的真实写照，所以选择A选项。
